No bc then it would be x squared

Step-by-step explanation:

No. If you distribute the 'x', you get:

y =  {x}^{2}  + 3x

The function is quadratic due to the exponetial term of x^2

ICE Princess25 [194]

Answer:37%

Step-by-step explanation:

There are 19 children, so the denominator is 19.

There were 7 playing dress-up, so the numerator is 7.

The fraction is \frac{7}{19}. 7/19=0.3684~0.37

To convert decimals into percentage, mulitply by 100 and use a percent sign.

0.37*100=37%

What is the solution to the system of equations? Use the substitution method. {y=−2x+5 3x−4y=2
GaryK [48]
We have that
<span>y=−2x+5 --------> equation 1
3x−4y=2---------> equation 2
</span><span>substituting 1 in 2
</span>3x-4*(-2x+5)=2--------> 3x+8x-20=2--------> 11x=22-----> x=2
y=-2x+5-----> -2*2+5-----> y=1

the solution is
x=2
y=1

Answer:

12) y=3x-15

14) y=-1/2x

16) y=13x-105

Step-by-step explanation:

Parallel lines always have the same slopes but different y-intercepts. So, we can make the equation (b is y-intercept of new equation):

12) y=3x+b

14) y=-1/2x+b

16) y=13x+b

now, we can plug in each of the coordinates given to these equations.

12) (4,-3): 4 is x, -3 is y.

       -3=3(4)+b

      simplify: b= -15

14) (-4,2): -4 is x, 2 is y

      2=-1/2(-4)+b

        simplify: b=0

16) (9,12): 9 is x, 12 is y

       12=13(9)+b

       simplify: b=-105

Now, plug in those numbers to your equation for b value.

12) y=3x-15

14) y=-1/2x

16) y=13x-105

*for 14 we don't need to write anything after -1/2x because b=0*
